The Soran High School rugby team is devoid of third-years. Riku, who found it odd, hears that the previous captain Nade Seiichiro quit playing rugby after an injury. After learning from second-year Oguma Keita about the circumstances of the time aside from the injury, Riku makes a certain decision.
I know how one big loss can 
become a wound that festers.
.أعلم ماهية أن تتحوّل خسارة كبيرة إلى جرح متقيّح
Ich weiß ganz genau, wie eine große Niederlage
zur Wunde werden kann, die nicht mehr heilt.
Je sais à quel point un échec
peut devenir une blessure
Sei que uma grande derrota pode
se tornar uma ferida que o consome.
Я знаю, как одно поражение
может стать вечно гноящейся раной.
